That’s a tough one. It’s been out of production for a long time, and it was a Japanese model so most of the documentation is in Japanese. Try this or this to start. Other than that, I only ever noted “2.2Ghz Celeron, 256Mb of memory, a 20Gb hard drive, USB2.0, an ATI Radeon 330-series graphics card on a 1024×768 LCD, a CDROM, Windows XP (in Japanese) and a floppy drive.” Sorry, I wasn’t much help.😦
